IPC: B22D11/20
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the segregation at the center part of thickness in a cast slab and to obtain the cast slab having high quality by setting the dividing position of plural rolls arranged in the drawing-out direction of the cast slab in a specified range from the end part in the width direction of the cast slab. SOLUTION: Plural pairs of rolling reduction rolls faced to each other so as to interpose the cast slab along the width direction of the cast slab, are arranged in the drawing-out direction near the position where the cast slab drawn out from a mold is tully solidified, and respective rolls are divided in the roll axial direction. The divided position of this rolls is set to be in the range shown with the equation: 0.5 × the thickness (mm) of the cast slab + 200 (mm). If the portion where the rolling reduction is executed to the cast slab with the upper and lower divided rolls, is the position of either of two rolling reduction rolls adjoined in the drawing direction, the segregation is hardly developed.  In other words, if the portion where the bearing position in both the upper and lower rolls does not exist, exists at one time or more in each pitch between two rolls adjoined in the drawing-out direction, the segregation is hardly developed.

Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To set accurately, rapidly, and easily the position of an electrode plate in relation to a grinding wheel, by equipping the grinding device with a feed mechanism moving the electrode plate toward and backward the grinding wheel and controller for positioning the electrode plate in relation to the grinding wheel by controlling the feed mechanism. SOLUTION: For example after polishing, when an electrode plate 32 is moved toward A up to the position shown by solid line to separate the electrode plate 32 from the grinding wheel 23, a NC device 70 drives a pulse motor 63 of a feed mechanism 37. At this time, the NC device 70 records the number of pulses of pulse current (driving current) supplied to the pulse motor 63 for moving the electrode plate 32 from the present position shown as two-point chain line to the position shown as solid line. When the operation restarts, the NC device 70 supplies pulse current of the amount corresponding to the number of pulses recorded. The pulse motor 63, that is the feed mechanism 37 moves the electrode plate 32 toward B up to the original position shown as two-point chain line.  Therefore, the gap between the electrode plate 32 and the grinding wheel 23 is accurately and rapidly set to the original specified gap value.

Title: Rolling-controlling apparatus for tractor working machine or such
Inventor: TAMAI SEISHIN
IPC: A01B63/10
Filed: 1988-08-12
Abstract: PURPOSE:To improve the measurement accuracy of the action time of a rolling cylinder and to enable smooth control of rolling by stopping the present rolling control output after the lapse of a prescribed time excluding the time performing the lifting operation by a lift control valve. CONSTITUTION:After the lapse of a prescribed period from the start of rolling control, the controlling action is stopped at the position to interrupt the rolling control in the same direction provided that the rolling control condition is maintained. The measurement is interrupted for a prescribed period during the period to output a lifting motion of a lift arm 12 with a lift control valve B and is continued for a prescribed period after the interruption of the lifting- side output of the lift control valve B. Since a lifting hydraulic circuit 4 contains large volume of oil and has high oil pressure during the output operation of the lift arm 12, the acting period of a cylinder 1 is measured in improved accuracy to enable smooth rolling control even if the supply of oil from a rolling hydraulic circuit 2 to the rolling cylinder 1 is almost terminated.

Title: Information recording device
Inventor: YOSHIDA MASAYOSHI
IPC: G11B7/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To enable the optimum power to be set regardless of whether there is any defect by storing a power setting value so as to make it correspond to positional information for identifying each unit test recording area, recording a test signal in the test recording area based on a recording clock signal, and forming the positional information at a cycle corresponding to the recording time. SOLUTION: With the defect detecting part detecting a defect and outputting its signal to the control discriminating part 19, an interruption processing is performed. At the time of defect detection, a power setting value is written in an area with an address value of 16-25 being a saving area, as well as in an area with an address value of 0-15 which is the original write area of dual memory 43. In the unit test recording area where a defect exists, no reproducing signal can be obtained corresponding to the power setting value; however, such signal can be obtained in the unit test recording area as a saving area.
